Pressure-measurement method for determining cylinder inner pressure in an internal combustion engine uses a cylinder pressure model with input values such as load, revs and crank angle

摘要

A pressure value (PDruckmodell) dependent on crank angle is calculated in a cylinder to form a modeled cylinder inner pressure (PGas) when corrected with a pressure-correcting value (delta PGas), which is created from a consideration of transitional moment on a crankshaft.
